What are the functional and non functional requirements of hospital management system?

Non Functional Requirements There are a lot of software requirements specifications included in the non-functional requirements of the Hospital Management System, which contains various process, namely Security, Performance, Maintainability, and Reliability.

How do you gather non functional requirements?

How do you discover and elicit non-functional requirements?Stakeholder goals, values, and concerns – Talk to the stakeholders! … Legacy system and/or existing platform constraints – the analyst takes a look at constraints dictated by the environment into which the new system must fit, the existing systems with which it must integrate, and the technical platform(s) it must use.More items…

What are the functional and non functional requirements of a library management system?

Non-Functional requirements: • Performance Requirements – Performance of the system should be fast and accurate. – System shall handle expected and unexpected errors. – Should be able to handle large amount of data. Safety Requirements – Must be two servers one main server and one backup server.

What is recoverability in non functional requirements?

Recoverability: The capability of the software to re-establish its level of performance and recover the data directly affected in the case of a failure. Availability: The capability of the software to be in a state to perform a required function at a given point in time, under stated conditions of use.

How do you describe functional requirements?

Functional requirements define the basic system behaviour. Essentially, they are what the system does or must not do, and can be thought of in terms of how the system responds to inputs. Functional requirements usually define if/then behaviours and include calculations, data input, and business processes.

What is security in non functional requirements?

Non-Functional Security Requirements Examples: The software must remain resilient in the face of attacks. The behavior of the software must be correct and predictable. The software must be available and behave reliably even under DOS attacks. The software must ensure the integrity of the customer account information.

What is scalability in non functional requirements?

Scalability is a non-functional property of a system that describes the ability to appropriately handle increasing (and decreasing) workloads. According to Coulouris et al. … Scalability competes with and complements other non-functional requirements such as availability, reliability and performance.

What are non functional requirements of a system?

Nonfunctional Requirements (NFRs) define system attributes such as security, reliability, performance, maintainability, scalability, and usability. They serve as constraints or restrictions on the design of the system across the different backlogs.

What is reliability in non functional requirements?

DEFINITION: Reliability is the extent to which the software system consistently performs the specified functions without failure. ELICITATION: Reliability requirements address the user concern for the system’s immunity to failure.

Which process model is used for hospital management system?

Hospital management system can be developed by using waterfall model which is a popular version of development life cycle model for software engineering. It describes a development method that is linear and sequential.

Where do you file non functional requirements?

Functional Requirements Document (FRD) Non-functional requirements are typically found within their own section in an FRD. This section usually follows the functional requirements and will be labeled “non-functional requirements”.

What is difference between functional and non functional testing?

Functional requirements are the WHAT; nonfunctional requirements are the HOW. So, the testing of functional requirements is the verification that the software is executing actions as it should, while nonfunctional testing helps verify that customer expectations are being met.

What is usability in non functional requirements?

most systems. A usability requirement specifies how easy the system must be to use. Usability. is a non-functional requirement, because in its essence it doesn’t specify parts of the. system functionality, only how that functionality is to be perceived by the user, for.

What is capacity in non functional requirements?

Capacity defines the ways in which the systems may be expected to scale-up by increasing hardware capacity based on the organisation’s volume projections. For example, transactions per seconds, customers online, response time, and so on. Capacity is delivering sufficient functionality required by the the end users.
